TO ALL WHOM IT MAY CONCERN:

Be it known that we, J. SMITH and J. F. IRWIN` of La Porte, in the county of La Porte, and State of Indiana,- have invented a new and useful improvementn Car-Coupling; and we do hereby declare that the following is afull, clear, and exact description thereof, which will enable others skilled in the art to make and use the=saine, reference being had to the accompanying drawings formingpart of this specification.

This invention relates 'to the method in which the coupling-bolt or pin is operated, and it consists in dra-w? ing the pin from the coupling-link, when the cars are to be uncoupledfby a slide which has a cogged rack attached to it, nd a pinion on a horizontal shaft, which works in the rackas will be hereinafter described.

Figure 1 represents a vertical longitudinal'section of the apparatus through thc line cv :v of fig. 2. f

Figure 2 is a top or plan view. A

Similar letters of reference indica-te like parts.

A represents the draw-head of the ear. B is the coupling-pin or bolt. C is the coupling-link, D is the slide which governsl the coupling-pin, with the rack attached to its under side. Eis the pinion. F is the pinion-shaft. G represents hand-wheels on the .pinion-shaft by which the shaft is revolved. The forward part of the slide D is in the form of a link, as seen in fig. 2, the inside forward part of which operates upon the pin. This slide is confined by guides a, attached to the draw-head, under which it Iis allowed a back land forward motion as it is Inoved by the pinion. The pin B is hung on a pivot, b, on the top ofthe draw-head. When the slide is drawn back the pin assumes'the position represented at d, fig. 1. 'This is done in uncoupling the cars. When the slide is thrown forward again the pin drops by its own gravity to a vertical position, as seen. The slide as it operates upon the upper portion of the pin near its pivot gives the end of the pin a rapid sweep through the slots e in the plates of the draw-head, to withdraw it from the coupling-link. vWhen the cars arev to be coupled the link of the opposite car strikes the pin and pushes it b ack till the end of the link passes beyond it, when the pin drops within the link and the cars are coupled. When the pin is elevated or raised from the coupling-link by the slide the pin is allowed to drop by throwing the slide forward again sothat the pin shall be ready for'coupliu'g. The end of the draw-head H is made solid, of any suitable metal, and with a mouth suiliciently'ilaring to receive and guide the coupling-link. The rack and slide may be operated from either side of the car or from the platform, and it will be seen that the cars are coupled automatically.

Having thus described ourinvention, what we claim as new and desire to secure by Letters Patent, is-

The slide D, the pinion E, the coupling-pin B, and the shaft F,'constructcd, arranged, and operating substantially as herein shown and described, in combination with the draw-head of a railroad car for the purposes set forth.
